About Keystone Compliance

3-Meter Chambers

Keystone Compliance has three ANSI C63.4 (NSA) compliant 3-meter, semi- anechoic absorber / ferrite lined chambers. These 3-meter chambers allow Keystone Compliance to perform full qualification, 3-meter measurements in the frequency range of 30 MHz to 1 GHz required by the CISPR 22, CISPR 11 and FCC Part 15 standards, as well as meet the field uniformity requirements of the EN 61000-4-3 standard. Further, to ensure these chambers continue to meet these evolving standards, they have been designed to perform testing up to and beyond 18 GHz.
